IFTTT - Unable to find send webhooks via service ifttt.trigger

I just setup (and restarted HA after setup) the IFTTT integration. I am able to receive webhooks from IFTTT, but I cannot send any.
The service ifttt.trigger is not available. When I create an action in the Automation UI it does not find that service, and when I triggered it in Developer Tools I get the following Log Errors:

Any thoughts why this service would not be available?

Here’s the Integration Page: IFTTT - Home Assistant

From what I understand (I had the same question) you may actually just want to send a webhook request as an action from an automation.
So basically, it just means that HA should call your webhook URL with the trigger you created in IFTTT.
(I agree this is not the documented approach, but this as well should work, although it is less flexible as each request has to be YAMLed).

I have found that it seems you can just to create a RESTful request using your maker webhook trigger URL as explained here :
[RESTful Command - Home Assistant](https://RESTful Command)
naming is you want (“webhook_1”) and saving it in YAML.
Like so :

rest_command:
  webhook_1:
    url:"https://maker.ifttt.com/trigger/webhook_trigger_name_1/with/key/YOURAPIKEYHERE/""

(You’ll need to restart Home Assistant once configuration.yaml is updated)

And then call it as “Action Type : Call Service”, and check for the option “RESTFul Command : webhook_1”

Let me know if this works.
(edited to clarify that this is an option, not the solution)

By the way, I managed to get the IFTTT service available by mnaually adding to configuration.yaml the entry :

ifttt:
  key: YOUR_IFTTT_API_KEY_HERE

So just adding the service in integration doesn’t seem to be enough.

Thank you! I’ll try that and if it does work I’ll do my first home assistant documentation PR.
